Mature Teratoma in the Adrenal Gland

ABSTRACT

A teratoma is a germ-cell tumor composed of tissue components representing derivatives of three germ layers. A teratoma in the region of adrenal gland is a rare retroperitoneal tumor. We now report a case of a primary adrenal teratoma. A 38-year-old woman presented with an incidentally detected adrenal mass. The computed tomography scan revealed a 9x8x7.5 cm fat density mass with calcification in the left adrenal gland. The surgically resected tumor was round and well circumscribed and the adrenal gland was present at the periphery of the tumor. The cut surface contained fat tissue and a hair containing cyst. Microscopically, the tumor consisted of adipose tissue, hair, skin appendage, nerve, muscle bundle and bone.
